Boss (on phone): You're good at Excel, let me ask you a question.
Boss: I want to put the variance of column A and column B in column C.
(After several minutes he explained that he actually wanted the word "negative" if the difference between A and B was negative and the word "positive" if the difference was positive. I double checked as clear as I could be about the actual word "negative" and the word "positive". Where he came up with variance I don't know)
Over the next 20 minutes I explain character by character how to create an IF function in Excel to accomplish this task, then...
Me: Then grab the little black square in the bottom right corner to copy the formula down the column.
Boss: What? Wow, I didn't know you could do that? (he's been using Excel for years) Wow, you saved me hours I would have re-typed all that dozens of times.
Me (stunned silence)
Boss: Wait!?! I don't want it to be words I want numbers
